Very Low Frequency (VLF) spectrograms show sometimes sets of lines called MLR (Magnetospheric Line Radiation) with frequency spacing close to 50 or 60 Hz. It is very tempting to attribute these MLR to Power Line Harmonic Radiation (PLHR). PLHR are the ELF and VLF waves radiated by electric power systems at the harmonic frequencies of 50 or 60 Hz. Here we show for the first time large scale MLR observed simultaneously on ground and on board a low altitude satellite which is flying over the same zone.

摘要-Impulsive噪音缓解了正交频分复用（OFDM）可以使用两个阈值剪贴归零方案来完成。我们引入一个新的结合脉冲噪声消除方法，称为clippingreplacement-归零计划，其中有三个考虑阈值：限幅阈Tclip，更换门槛TREP和归零门槛Tnull。当接收到的OFDM样本的幅度高于TREP和下方Tnull我们将其设置为所述平均幅度JX？无噪声的OFDM样本第j。模拟结果表明，附加的动作，替换动作，与TREP的一个很好的选择带来在误码率的降低。
